Chainsaw Repair

Do you have to remove paint before JB weld or steele putty? If I ever need to I'll try your redneck fix. Although hope I don't have to.

Well I am learning the 475 and 425 differ.

 After spending 2 different days trying to remove the 475 clutch, today I succeeded. Once the clutch was off and oiler removed I realized it has the metal pressed on worm gear on crankshaft.  Guess I should have realized this when it didnt have the same clutch drum as 425 and plastic worm gear.

So right now I am stuck at coming up with a worm gear removal tool for the 475.

Also one side of the 425 crank bearings is different then the standard bearing used on opposite side and on both on 475. That 425 side seal is different too.

Saving info from another running into this on a 2077 oiler redo. OEM part number for worm gear puller  502540901

((The original gear on the crankshaft was steel,15 mm I.D., 18 mm O.D. on the sealing surface, 16.5 mm overall height/length, and about 22.43 mm O.D. on the gear teeth.

The replacement I ordered (503 72 36 01) is plastic and intended to drive off the clutch, 17 mm I.D., 19.75 mm O.D. on the sealing surface, 15.15 mm overall height/length, and about 22.2 mm O.D. on the gear teeth.

All measurements above were made with the dial caliper and converted to mm so they may be off slightly.))

Forgot to mention I had to use a afm 52mm piston for now.
The oem piston ring is stuck in the groove and I havent been able to get anywhere with it for a few weeks.  Looks like it will be making a trip someday to Al Smith's place for the kroil treatment. 

Used 425 tank on 475 also. Have 2 bare 475 tanks on the shelf.

475 is running now  .  I am still way short on parts to complete it but hey who need it anyways.   

I used a afm solid style 52mm 372 piston  . Slipped right in with no mods to it.   

Learned that the cranks look just like a husky crank I have on the shelf too.  Just need to put calibers on them. But they look identical. Also learned a air filter I can use in flocked style instead of mesh for the filter types I use on these.
